可执行行为和π演算(扩展抽象)

Executable Behaviour and the π-Calculus (extended abstract)

Bas Luttik, Fei Yang

摘要:

反应式图灵机扩展了经典的图灵机,具有对可观察的交互行为进行建模的功能。当且仅当一个行为在行为上等价于反应式图灵机的行为时,我们称之为可执行行为。在本文中,我们研究的可执行行为和行为之间的关系,可以指定的π演算。我们建立了所有可执行的行为可以指定在π演算的分歧保持分支双相似性。然而,由于反应式图灵机模型的(预期的)限制,相反的情况是不正确的。也就是说,π演算允许指定的行为是不可执行的分歧保持分支双相似性。出于对可执行性的直观理解,我们考虑对与每个pi项可执行行为相关联的pi演算的操作语义的限制,至少到不需要保持发散的分支双相似性的版本。

英文摘要:

Reactive Turing machines extend classical Turing machines with a facility to model observable interactive behaviour. We call a behaviour executable if, and only if, it is behaviourally equivalent to the behaviour of a reactive Turing machine. In this paper, we study the relationship between executable behaviour and behaviour that can be specified in the pi-calculus. We establish that all executable behaviour can be specified in the pi-calculus up to divergence-preserving branching bisimilarity. The converse, however, is not true due to (intended) limitations of the model of reactive Turing machines. That is, the pi-calculus allows the specification of behaviour that is not executable up to divergence-preserving branching bisimilarity. Motivated by an intuitive understanding of executability, we then consider a restriction on the operational semantics of the pi-calculus that does associate with every pi-term executable behaviour, at least up to the version of branching bisimilarity that does not require the preservation of divergence.
